DUMP-BED FOR WAGONS.

Specification of Letters atent.

Patented July 3, 1906.

Application lled July 15, :i905i Serial No. 269.853.

To all whom AL15 may concern:

Be it known that We, WILLIAM F. HIATT and Oris E. GULLEY, citizens of the United States, residin at Danville, in the county of Hendricks enf State of Indiana, have invented certain new and useful Improvements in Dump-Beds for Wagons, of which the iollowing is a specification.

This invention relates to improvements in dump-beds for wagons.

The object of the invention is to provideaV quick and easy means for swinging the longitudinal section ofA the hed from a normal horizontal position to a practically vertical position for the discharge of the contents of the bed by gravity.

We accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an end view oi the bed having our improvement, the view showing the bed in a closed position for holding the material to be carried by the wagon. Fig. 2 is a view of the same end with the section at the bottom moved into open or dumping position. Fig. 3 is an under side plan view of the wagon-bed with the bottom sections in their closed position; and Fig. 4 is a detail in side elevation of a side of the bed, showing the an rangement of one of the bottom-holding devlees.

Like characters of reference indicate like parts throughout the several views of the drawings.

1 represents the sides of the wagon-bed, and 2 the ends, all of usual construction, The bottom of the bed is formed out of longitudinally-placed boards 3, here shown` as four in number. Bolted to the ends of these board-sections are the plates fi, each having trunnions 5, which are inserted in holes bored in the ends 2 of the bed, whereby the sec-tions 3 are hinged in a manner to permit seid seetions to swing downwardly on trunnions 5, acting as hinges. The longitudinal edges oi' the sections 3 will preferably be beveled in the manner, as shown in Fig. 2, to act as stops for each other in compelling the sections to form an even horizontal bottom for the hed.

Bolted to the under sides of the seotions 3 are the hangers 6, each of which has a lateral extension with an end perforation, hy means of which the hanger is pivotally secured to a bar 7. The hangers are arranged in transverse rows across the under side of the bed,

I and those of each row are pivotally secured to the same bar 7. When the bed-bottom is in its olosed position, the sections forming said bottom are retained in this position of closure hy securing the ber 7, andthe weight of Ythe load carried by the wagon-bed is virtually supported hy said her As rneny of these bars may be used as may be desired. The drawin s show three bars, which are sufiieient for all ordinary purposes.

Mounted in suitable journal-boxes 8 on the outside of the bed are the rods 9, which extend longitudinally of the bed and have the downwardly-cranked portions 10 to support the projecting endV of the bars 7 in the manner as shown in the drawings. The forward ends of these rods 9 are bcn t at right angles to form cranks to assist in rocking said rod. The rods will be rocked for the purpose of swinging their cranked portions l@ out of engagement with the harsV 7, thereby removing the support for said bars and erinitting the bottom sections of the hed to rop down into position for the discharge of the load.

12 is e shaft mounted longitudinally of the bed, on Vthe underside of the latter, in suitable boxes 13. The inner end of this shaft is bent at right angles to forni the cranks 14, and the end of this crank is bent at right angles and is passed through the adjacent hangers 6 and the bars 7, so as to serve as the pivot conneoting those parts. The outer or front end of the shaft 12 is bent up to form the lever extension 16. 17 is a rack-bar secured to the front end 2 of the wagon-bed. The lever 16 operates between the rack-har l? and the end 2 and hears by the resilieney of the lever against the rack-bar so as to cause the lever to engage with the notches of the rack-oar and hold a given adjustment of the lever. The cranks on the ends of the bars Q, which have been previously referred to, are shown at 20. One of these extends in an upward direction, while the other is extended in the reverse or opposite direction, while the bars are serving as a lock. The two cranks 2() are connected, by Ineens of the rods 22, with the lever 16, whereby when the lever 16 is shifted the bars 9 will be correspondingly rocked to engage with or release the bars 7.

To make the engagement between the cranks l() and bars 7 a little more secure, we prefer to form the indents or notches 24 on the under sides of the bars 7 to receive the said crank members 10, and to reduce the ICO friction between the cranks and bars 7 in the engagement and disengagement of these parts we provide the rollers 26 on the cranks 10.

W' hen the bed is in the closed and locked position, (shown in Fig. 1,) a movement of the lever 16 toward the left will cause the bars 9 to be rocked in a direction to cause their cranked portions to swing outwardly, thereby disengaging the ends of the bars 7, and at the same time the inner cranked end 14 of shaft 12, of which the lever 16 is apart,will cause the bar 7 to be moved in a downward direction, thereby causing the sections 3 of the bottom of the bed to swing down into the position shown in Fig. 2, which causes the oad in the bed to discharge by gravity between said bottom sections 3. After the load has been discharged the lever 16 is returned to the position shown in Fig. 1, which returns the sections?) of the bottom of thebed to their horizontal positions and also rocks the bars 9 back into the position shown in Fig. 1, with their cranked portions supportin the ends of the bars 7.

Iaving thus fully described our invention, what we claim as new, and wish to secure by Letters Patent of the United States, is-

1. In a dump-bed for wa ons the combination with the sides and en s of the bed of a bottom in longitudinally-divided sections, said sections being hinged to swing downwardly from one edge, hangers depending from said sections, cross-bars pivotally secured to said hangers and extending beyond the sides of the bed when the bars are in closed position, a shaft having a cranked end to raise and lower the cross-bars when the shaft is rocked, a hand-lever to rock the shaft, a rack-bar to engage and hold the lever, bars mounted on the outer sides of the bed, said bars having cranked portions to engage and support the projecting ends of said crossbars, and means connected with the lever for rocking said bars having said cranked portions.

2. In a dump-bed for wa ons the combination with sides and ends, o a bottom in longitudinally-divided sections, said sections being hinged at one edge so as to allow the opposite edge to swing downwardly, hangers on the under side of said sections, cross-bars pivotally secured to said hangers, the ends of said bars projecting beyond the sides of the bed when the sections of the bottom are in their horizontal closed position, said crossbars having indents on their lower edges, bars longitudinally of the bed, mounted on the outer sides of the latter, said bars having cranked portions to engage the projecting ends of the cross-bars, friction-rollers on the cranked portions of said bottom, and means for rocking the longitudinal bars to engage and disengage the cross-bars.

In witness whereof we have hereunto set our hands and seals at Danville, Indiana, this 1st day of July, A. D. 1905.
